Specification of `Letters Patent.

Patented May 14, 1912.

Application filed February 2, 1911. Serial No. 606,119.

To all whom t may concern:

Be it known that I, EARL T. ADAMS, a citizen of the United States, and a resident of Portsmouth,` in the county of Scioto and State of Ohio, have made certain new and useful Improvements in Buttonhole-Markers for Shoes, of which the following is a specification. i

My invention relates to improvements in devices for marking button-holes for shoes, and it consists in the combinations,'construc tions and arrangements herein described and claimed.

An obj ect of my invention is to provide a device by means of which all the buttonholes for a shoe may be marked at one operation thereby making a saving of the time consumed in the marking operation.

A further object of my invention is to provide a novel marking device in which the number of button-holes to be marked may be varied while still maintaining the proper relative distances between the marks.

A further object of my invention is to provide a device in which the position of the marking point-s may be accurately gaged by the mere act of placing the piece to be marked in proper position.

A further object of my invention is to provide novel mechanism for accomplishing the above named objects.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which-W Figure 1 is a plan view of the device; Fig. 2 is a vertical section; and Fig. 3 is a horizontal section along the line 3-3 of Fig. 2.

In carrying out my invention I provide a table or support consisting of a top 1 and legs 2. The top is provided with a series of radial slots 3. Secured to the table-top are a series of curvedmetal plates 4, these plates being arcs of circles, and the edges of the plates registering with the slots 3 in the table as clearly shown in Fig. 1.

Disposed centrally beneath the table upon the floor, or other stationary support, is a hollow standard 5 arranged to receive a rod 6 which is kept in a normally raised position bymeans of a spiral spring 7. The standard 5 has an arm 8 which projects upwardly and to which is pivoted a Z-shaped lever L, the lower end of the lever being formed into a treadle T.' The lever L is slotted at M to receive th-e pin 6a which is carried by the rod, or plunger 6.

Referring now particularly to Figs. 2 and 3, it will be seen that the plunger 6 has laterally extending arms 9, which bear at their extremities an arc-shaped rod 10. Disposed on' the rod 10 is a series of bell-crank levers each consisting of an upper portion 11a, and a lowerportion 11b, as shown in Fig. 2. The upper portion 112L extends through the slot 3 and each of these upper portions is provided with an adjustable marking device 12, having on its lower side a pin 13 which is removably secured by means of a set-screw 14, and which is designed to prick a hole in the pieceto be marked. The body portion 12 of the marking device may be adjusted toward and away from the bars 4 by means of the setscrew 15. The lower portion 11b of the bell-crank lever is provided with an adjustable weight 16'.

In Fig. 1 I have shown each plate 4 as being provided at its outer end with a spring 17, having a bent portion which eX- tends across the space between the plate upon which it is located and the adjacent plate.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Let us assume that the operator has been instructed to mark the positions of ten button-holes on the fly of an upper of given size. She pushes the markers 11 to 15 outwardly, the levers 11EL passing through the slots until the spring catch 17 is reached. Pressure on the lever cams aside this spring catch which, when the lever has passed, springs into place thereby holding the lever locked in position against the force of the weight 16, which, of course, is swung upwardly when the lever is pushed outwardly. The markers 11 to 15 have then the position shown in dotted lines in Fig. 1, where they are out of the way of the fly. The edge of the y to be marked is then placed against the remaining markers. The latter are so balanced by means of the weights 16 that they move at the slightest pressure. The fly is then pushed outwardly until the fiy is in the position shown in dotted lines in Fig. 1, and the markers are in the position shown in dotted lines. Pressure on the foot lever T causes the plun er 6 to descend carrying downwardly With 1t all the markers. It Will be noted that these markers are turned so that the points will enter the fly While the metal strips serve as anvils. 'Ihe buttonholes are thus marked simultaneously. On removing the fly the markers return to their original positions through the action of the Weights 16. If eight button-holes are to be marked, then the iirst eight markers are used, the remaining markers being held out of the way by the springs 17. If a larger ly is used the button-holes will be farther apart, but in each instance the positions of the button-holes may be accurately' determined by pressing the iy against the markers until the latter have been pushed far enough to just accommodate the number of markers selected. A slight pull on the levers which have been held out of the Way Will force them past the spring, when they will return to their original positions.

The device described above obviates the necessity of marking the individual buttonholes by hand. The button-holes are always properly spaced and the Work of marking the button-holes is greatly accelerated.

I claim:

l. In a button-hole marking device, a series of marking points, means permitting the movement of the marking points along radial lines, a series of anvils disposed beneath said marking points, means or'causing a simultaneous movement of said marking point-s toward said anvils, and automatic means for returning said marking points to their original positions.

2. In a button-hole marking device, a series of bell-crank levers, an arc-shaped support for said bell-crank levers, a series of marking devices carried upon the upper end of said levers, a series of arc-shaped anvils for said marking devices, and means for moving said levers simultaneously to cause the movement of said marking devices toward said anvils.

3. In a button-hole marking device, a series of bell-crank levers, an arc-shaped support for said bell-crank levers, a series of marking devices carried upon the upper end ot' said levers, a series of arc-shaped anvils for said marking devices, and means for moving said levers simultaneously to cause the movement of said marking devices toward said anvils, said means comprising a plunger, aspring for maintaining said plunger in a normally raised position, lateral arms secured to said plunger for supporting said arc-shaped rod, and a tootlever for actuating said plunger. l

4. In a button hole marking device, a series of marking points, means permitting t-he movement of the marking points toward or away from a common center, a series of anvils disposed beneath said marking points, the space between said anvils serving as guide slots for the marking points, and means for causing a simultaneous movement of said 'marking points to- Ward said anvils. y
